Begin with the basics of an installation project

If you're not sure whether you need a new off-mains system — or even where to begin — you're not alone. Most homeowners start their installation project with more questions than answers.

We've covered the most common ones to help you move forward with confidence.

When you're ready to move forward

Your installation project moves through a series of steps before your new system goes in the ground. Each step listed below has a specific purpose, and each one needs to happen before the next can begin.

That might sound daunting, but it's straightforward when you have the right help. We guide you through every stage, handle the technical work, and keep you informed throughout.

You never need to be an off-mains expert or a project manager — that's our job.

You don't have to figure this out alone

An installation project has lots of moving pieces. For most homeowners, this is unfamiliar territory — and coordinating it is time-consuming and stressful.

That's exactly what Ecoflo is here for.

Our team is your single point of contact throughout your project. You don't need to chase contractors, manage timelines, or decode regulations. We handle it and keep you informed at every stage.

Many Ecoflo services are free, including your site assessment, system design, and regulatory guidance. When costs apply, we'll walk you through them before any work begins.

From your first question to your final installation, you're in good hands.

Frequently asked questions

Start with our free site assessment. We check your system against the General Binding Rules — the regulations that govern off-mains systems in England and Wales — and tell you whether it's compliant. If it's not, we'll explain your options and next steps. There's no cost and no obligation.

Request a free assessment

In the UK, most projects take 1 to 3 months from the first assessment to final handover after installation.

The exact timeline depends on how quickly each stage progresses — including any regulatory approvals your project requires.

The best way to avoid delays is to work with an end-to-end service provider like Ecoflo. As your single point of contact, we handle every stage, so there's no time lost to handoffs between multiple contractors.

Tell us about your project

Our team is typically on site for about a week to complete excavation and the physical installation.

We understand that this is your home, not a job site. We tidy up at the end of every working day, minimise disruption to access routes, and keep you informed throughout.

In most cases, you can continue your daily routine without any significant disruption.

Yes. We've installed off-main systems across the UK, including some of the most remote corners of the country. Wherever your property is, we can help.

Tell us about your project

No. Think of our services as building blocks — you can use as many or as few as you need. Our free site assessment, for example, comes with no obligation to use us for your soil testing or septic design.

That said, there is one important condition: we design and install only our own products. If you choose our free design service, installation must be carried out by us.
